Duplicate metadata cluster detection at scale
Large websites need duplicate title and description detection that groups pages into reusable clusters instead of dumping endless one-line warnings.

Why duplicate metadata reports become unusable
On medium and large sites, duplicate title and description reports can explode into hundreds or thousands of rows. That volume creates the illusion of insight while making it harder to see the real issue: repeated templates or bulk content patterns.
Cluster-first analysis is the better model
Instead of reporting every duplicated string as a separate event, group pages by repeated title pattern, repeated description pattern, and affected template family. That gives teams a smaller and more accurate list of real causes.
- Cluster pages by repeated title values
- Group by template or page type when possible
- Estimate affected URL volume per cluster
- Highlight clusters that impact key landing pages first
What the UI should show
A useful UI should show the duplicated pattern, how many pages are affected, example URLs, and a likely source. Teams can then decide whether they need a template rewrite, a feed improvement, or editorial work.
This is usually a systems problem
Metadata duplication at scale rarely comes from human forgetfulness. It usually comes from CMS defaults, product feed fallbacks, or route-generation logic. Reports should guide people toward those systems quickly.
